Twisted functoriality in nonabelian Hodge theory in positive characteristic
arXiv:2105.01385
Abstract
We establish the twisted functoriality in nonabelian Hodge theory in positive characteristic. As an application, we obtain a purely algebraic proof of the fact that the pullback of a semistable Higgs bundle with vanishing Chern classes is again semistable.
